a spring loaded non-return valve prevents back feeding of gases which stainless steel filter (100 µm) in the gas inlet protects Natural gas (M).

Choose from our selection of non-return valves, including threaded check valves, flanged check valves, and more. In stock and ready to ship. Natural Gas: Neon: Nitric Acid: Nitrogen: Oil: Oxygen: Phosphoric Acid: Potable Water: Propane: Refrigerant: Welding Gas Check Valves for Regulators. Stop the reverse flow of gas in your regulator.

NON-RETURN VALVE ULTRA 10 WITT non-return valves for reliable protection against dangerous reverse gas flow. Flow-optimised valve system causes very low pressure drop at minimal noise emission. Every non-return valve 100% tested. Operation / Usage non-return valves are used to protect equipment and pipelines against dangerous reverse gas flow.

Non-return valves are safety devices to prevent backfeeding of gases. WITT non-return valves protect plants, pipelines and outlet Non-return valvepoints against reverse gasflow. They can also be used in accordance with EN 764 section 2 in applications where the maximum temperature does not exceed 70° C (158° F).

Spring Check Non-Return Valves. Spring Check Non-Return Valves are simple, low cost but systems for air, gas or low pressure applications where bubble.

We are manufacturing two types of Non - Return valves. V - 6301 is having metal to metal seat and is suitable for high pressure applications upto 200 Kg/cm2. V- 

Check valves (Non Return valves); provide engineers and installers with an inexpensive and reliable method to prevent the backward flow of a liquid or gas.

18. This applies to NRVs for the use on first and second family gases for installations of maximum operating pressure not exceeding 7 bar. It does not apply to 

Europa Valve has recently completed an order of 6x 30” Class 600 Non-Slam Check Valves for a customer in the Middle East. Installation Location: Middle East. Description: 30” 600 RF Non-Slam Check Valve. Service: Natural Gas transmission. These valves have a duplex trim. The complete manufacturing of these valves, including a specialised

non-return valves (check valves) are proved in accordance with DIN EN ISO 5175-2. They may also be used as a safety device to protect against flashbacks (proved in accordance with DIN

30” 600 RF Non-Slam Check Valves ready for shipping Non-Slam Axial Flow Check Valves like these go through design and manufacture here in the UK. After production, they are then shipped to the Middle East, where their service application is a Natural Gas

Process safety dictates: Gas non-return valves are needed to prevent the dangerous backflow of gases and the formation of unwanted mixtures in plants and 

And, even if hot combustion gases made their way back into the fuel nozzle/fuel supply piping there would likely not be sufficient air/oxygen for combustion to occur. GE-design heavy duty gas turbines use check valves (non-return valves) in the liquid fuel line primarily as part of the pressure atomization equipment.

Gas non-return valves for town gas, grid gas, natural and liquid gas, Methane (cleaned Biogas), Hydrogen, Oxygen, Nitrogen, inert gases and compressed air.
